Scope

1.1 Scope of EN 1991-1-9
(1) EN 1991 1 9 gives principles and rules to determine the values of loads due to atmospheric icing to be used for following types of structures:
- masts;
- towers;
- antennas and antenna structures;
- cables, stays, guy ropes and similar structures;
- rope ways (cable railways);
- structures for ski-lifts;
- buildings or parts of them exposed to potential icing;
- special types of structures, such as towers for transmission lines and wind turbines.
NOTE Atmospheric icing on electrical overhead lines is covered by EN 50341-1.
(2) EN 1991-1-9 specifies values for:
- dimensions and weight of accreted ice;
- shapes of accreted ice.
(3) EN 1991-1-9 cover types of icing, ice loads acting on structures, and falling ice considerations.
NOTE For wind actions on iced structures, see EN 1991-1-4.
1.2 Assumptions
The assumptions given in EN 1990:2023, 1.2 apply.
EN 1991-1-9 is intended to be used with EN 1990 (all parts), the other parts of EN 1991 and EN 1992 (all parts) to 1999 (all parts) for the design of structures.
